TRACTION-WHEEL ATTACHMENT.

VGran'ge,"in the county of Cook and [itate of Illinois, have invented certain new and use: l mp o emen s in T a tion-Whee A r tachments, ofwhich the following is afull,

' clear, and. exact specification- My inv nti n r ate o l gs for ac ion wheels, such as used more harvesting machines.

It has been-found-n s ry in. een e tien with the e o harv sting ma hines n muddy l t pre ide supp menta traction lug 11 th arveste wheels order o p e n the heel fr m slipping-rand o iv the desiredrtraction tn the machine. H his form of oonstructien is especially necessary on rice harvesting machines since the soil in the rice. field's is muddy, and is often cove red' with wat r when, he rice is'har est d- The present invention has, for. its object, o p o i a c nstruc on that sh ll meet he ne dse eve ou lined, and will pr vide sufiicient traction to enablethe harvester to per e s c s ful y under all c nd t ons A further object is to provide a supple: m n al tra n de ic that can he us d in connection with a regular harvester wheel en ed, b t hich wi l. p rmit of. the wheel being usedunder ordinary conditions without the supplemental device. With the accomplishment of the above de, fined objects "inqview l have provided a traction wheel with supplemental traction P r icularly on devices, such as raised portions, to which may be secured outwardly projecting lugs. The. Y suppl men al ac ion evices m v be formed on the periphery of the wheel, or may be carried byplates that are adapted to be secured to thevvheel,

In the drawings 1 have illustrated One embodiment of my invention, ands Figure 1 shows a plan View of a portion of theharvester wheel equipped with my improved traction lugs; i

Since these bolts pass through the ribs 1 5, through the longitudis nal bore of the raised portions of the plates, and through the outerfwall of the lugs, it Will, be that the lugsand their inwardly projecting portions 19 are securelyheld on the platesand to-thef periphery of the traction he When. t e o l on wh ch he chine is being operated is not muddy, the raisedportions 1 27 onthe plates which are secured" to the traction wheel will provide sufiicient traction forthemachine, and the suppl me l lug ar no u wever, when the machine is used, for instance in harves hgrri e, and e s i y, t

channel around the circumference of the traction wheel, and may act as a guidefora scraper secured to the frame of the harvester which scrapes the dirt and mud from the periphery of the wheel.

My improved supplemental lug maybe easily and quickly applied to the wheel, and when applied is securely held in place, and under changed conditions may be readily and quickly removed. g

While I have, in the above specification, described one embodiment which my inven tion may assume, "it will be understood that modifications may be made without depart ing from the spirit and scope of my invention as expressed by the following claims.

. What I claim as new is: l.

1. A traction wheel having in combination a series of plates secured thereto, said plates havingtransversely' disposed spaced raised portions-thereon, each of said raisedportions having a longitudinal 'bore therethrough adapted toreceive a retaining bolt whereby a supplemental lug may be secured thereto.

2. In combination,.a'traction wheel having a plurality of outwardly extending traction lugs secured to the periphery thereof and having longitudinal bores, 'a plurality of supplemental lugs, and means passing through the bores of. said first named lugs for securing said supplemental lugs thereto. i j

'3. A traction wheel having in combination a series of plates secured thereto, said plates having raised transversely extending p012 tions disposed in staggered relation around the circumference of the wheel, each of said raised portions havingia longitudinal bore therethrough, and a supplemental lug adapted to be secured to eachof said raised portions by means passing through the longitudinal bore; Y e

4:. A traction wheel having in combination a series of plates secured thereto, saidplates being provided with transversely extending raised portions, longitudinally extending ribs disposed at one end of said raised portions, and supplemental traction lugssfecured to said longitudinal ribs and raised portions.

- 5. A traction wheeljprovided on its periphery with a series of transverse raised portions, a series of vertical ribs disposed at one end of said raised portions, and supplemental lugs secured to said raised portions and to said ribs. V

6. A traction wheel having in combination a series of transverse raised portions disposed in staggered relation around the periphery of the wheel, a series of longitudinal ribs disposed at one end of said raised portions, said raised portions having longitudinal'bores therethrough, said ribs having spaced apertures, and a series oflugs adapted to be secured to said raised por-; tions and longitudinal ribs by outwardly extending projections engaging in the apertures of said ribs and means extending through the longitudinal bores;

7. In a traction wheel, a transverse raised portion,: -a longitudinal r1b disposed at one end of said transverse raised portion, and a tract-ion lug secured to said transverse portion and to said rib.

8. A traction 'wh'eel having in combination a transverse raised portion provided with a longitudinal bore, a longitudinally disposed rib at one end of said raised portion and having spacedapertures therein, a lug having projections registering with said apertures, said lug extending on one side over the end ofsaid transverse raised portion and having anaperture registering with the longitudinal-bore therein, and securing means engaging in the longitudinal bore and aperture. V, I i i f 9. Incombination, atraction wheel having a a plurality v of outwardly extending transverse traction lugslcarried by the periphery thereof, supplemental lugs adapted to'be secured to said transverse lugs, and means passing through said transverse lugs andsaid supplemental lugs for securing said supplemental lugs to saidtransverse lugs.

I 1 0. In combination, a tractionlwheel having a plurality of outwardly extending 1ongitudinally V bored traction lugs v carried by the periphery 5 thereof, supplemental lugs adapted to besecured' to said first named lugs, and means for securing said supplemen- .tal'lugs to said first named lugs; passing through the longitudinal bores of said firstnamed lugs; V Z

11. In combination, a traction wheel having 'a plurality of transversely disposed raised portions on "the periphery thereof, and longitudinally extending ribs disposed at one end of said" raised portions, a suppplemental lug, and means passing through said transversely disposed raised portions for I securing said supplemental lugs to said raised portions and saidribs. i

' 12. A supplemental traction device adapt ed to be secured to a traction wheel, and comprising-1a plate provided with-transversely extending raised portions, longitudinally extending ribs disposedat one end" of said raised portions, .and supplemental traction lugs secured to saidlongitudinal ribs and raised portions. V

13. A' supplemental traction device adapted to be secured to a traction wheel, and comprising a plate havinga transverse raised portion provided with a longitudinal aperture therethrough, a longitudinally disposed rib located at one end of said raised portion, and a traction lug secured to said raised portion and said rib by means passing thrOughthe'longitudinal. bore.

ing a smooth periphery, traction lugs secured to the periphery and extending radially'outward therefrom, hollow V-shaped auxiliary lugs fitting over the traction lugs and means outside the periphery of the wheel for securing the auxiliary lugs to the traction lugs.

15. In combination, a traction wheel, traction lugs secured to the periphery of the wheel and extending radially outward therefrom, hollow auxiliary lugs fitting over the traction lugs and means passing through the traction and auxiliary lugs outside the periphery of the wheel for securing the latterto the former.
